The number of web users who are facing browser-hijacking programs like N01.biz throughout the web continues to rise at an alarming rate. Despite the absence of any dangerous functionality that is typical for computer viruses or malware like Ransomware, Trojans or Rootkits may have, such software pieces can be very annoying. Most browser hijackers like R3.o.lencr.org, Humisnee.com tend to spam the screen with different banners, pop-up ads and redirect messages that cannot be removed. Besides, these programs can alter your favorite browser settings and expose you to questionable web content and unfamiliar websites. They can install a new search engine, place a new toolbar or browser extension or change the URL of your preferred homepage or new tab page without requiring your permission.


You probably already know what we are talking about because N01 has probably made some of these changes in your browser and has left you wondering how to remove them. The name of this application can often be found on popular forums for system security as a lot of people have been asking a number of questions about its purpose and its effect on their computer. This article also gives an explanation on these questions and guidance on how to uninstall this browser hijacker and how to remove all of its modifications from your device.

What is browser hijacking and is your machine in danger?

Browser hijacking is performed when you see that the settings of your main web browser have been updated without your permission and now all it does is it automatically redirects you to various websites that are filled with aggressive advertisements, banners, and pop-ups. Browser hijacking may occur if new software is installed in the system and the configuration changes during the installation, or if some automatic software updates, including browser updates, happen on your computer.

If your browser has been hijacked by N01.biz in particular, here is what you can expect:

  • The default homepage can be modified and a new URL may load every time you start the browser.
  • The standard search engine may be replaced by a different one that generates sponsored search results.
  • You may experience redirects to sites that you don’t have the intention to visit.
  • Various ads that aren’t necessarily connected to the website you are currently on can appear on the screen.
  • You can see new toolbars and buttons in the taskbar of your browser.
  • You can see new or updated favorites and bookmarks.

None of these changes are fatal for your overall system’s health. Yet, they can still be irritating and can prevent you from using your browser the way that you are used to.

Therefore, if you encounter any difficulties in your surfing and you are not able to get used to the changes and messages enforced by N01.biz, you have a right to remove the software. The good news is that it’s not that difficult to deal with a browser hijacker. All you need is to use a reliable removal tool or carefully follow a specific set of removal instructions in order to uninstall all of the enforced adjustments. For your convenience, below we have prepared a detailed guide dedicated to removing N01.biz. There is also a professional removal tool for automated support which you can use to scan your system for other potentially unwanted programs, Ransomware, Trojans and computer viruses.

    Hold together the Start Key and R. Type appwiz.cpl –> OK.


    You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

    Type msconfig in the search field and hit enter. A window will pop-up:


    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

    1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
    2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
    3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



    • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

    Right click on the browser’s shortcut —> Properties.
